29 Fig. 5 is a section on the line V-V, Fig. 2; Fig. 6 is a section on the line VI-VI, Fig. 1, showing the headlight lens; and

Fig. 7 is a section on the line VIIVII, Fig. 1.

Motor vehicle 1 is shown as equipped with headlight 2, tail light 3, stop light 4, and parking light 5.

The headlight 2 is shown as equipped with a lens 6 having centrally on the inner side thereof a duco coated, mirrored .or silvered back or reflecting portion 7. As so positioned this reflecting section provides a central opaque dimming portion as to the light emitting filament in the bulb in the headlight, while should the automobile 1 be left standing, say in daylight until after nightfall, or through some mishap or accident the headlight not be effective as a source of illumination, the reflecting portion 7 in receiving rays from an approaching headlight will refiect such back toward the driver of an oncoming car, so that such driver may readily locate by such reflection that there is an object to be avoided. This is an automatic return indication and a safe-guarding device at all times operative. It is never-of an intensity to approximate a glare, but is readily and easily located by the return rays. The tail light 3 is shown as equipped with a circular lens 8 having light transmitting central portion 9 and concentric therewith light transmitting ring 10. These are effective, when the bulb in the tail light 3 is illuminated, to disperse a general rear traflic signal, tending to diffuse throughout for disclosing the lens color to an oncoming driver. However, should the bulb in the tail light 3 be not lighted, the head lights of an oncoming car may direct rays of light through the lens 8 to strike reflecting portions or mirror rings 10, 11, to have such white light or yellow light rays reflected back as colored-rays from the lens 8, thereby visibly indicating to the oncoming driver necessity for caution in avoiding the carrier of such indication. Of course, it requires a. source of illumination in the tail light 3 to disclose from such light license number 12.

On fender 13 is mounted the parking light 5, having rearward colored lens 14, and forward clear, yellow or other colored lens 15. With parking light 16 on, light transmitting rings 17, 18, respectively of the lens 14, 15, diffuse light for general warning indication of the parking location of the vehicle. With the light 16 off, any approaching strong light will have rays therefrom strike inner central light ray reflecting back portions 19, 20, respectively of the lenses 14, 15. Accordingly as the lens is clear or colored, light rays are automatically of like indication, and diffusion is efl'ective in conjunction with outer reflecting rings 11. These reflecting portions are coatings,.opaque on the back and lustrous toward the glass 'or lens portion so coated.

When the stoplight 4 has its bulb 16 lighted, light rays therefrom maypass and be diffused by lens 21, having light transmitting ring portion 22. With the light ofi, central back coated reflecting portion 23, in conjunction with reflecting coating ring 11, may dif- I fuse rays striking this lens 21, to make the lens clearly ,visible as a stop signal. -However, this operation is continuous at all times the light rays are toward the lens 21, and is in dependent of any driving or control actions of the vehicle operator.

As a traflic-signal, even without asource of l ght, standard 24 may carry lens 25 having light transmitting ring 26 about reflecting 4 of thelens 25, may from his headlights get a reflection from the reflecting coating 27, while a driver from the opposite direction mayhave the traffic signal located by observing reflected rays from the ring 11.

For assisting in the diffusion, countersunk portions28 have the shoulders 291thereabout provided with coating 30 extending only partially of the height of the shoulder 29 from the countersink 28. In practice this seems to be of value in dispersing the light rays, with colored'lenses especially, so that the full lens extent appears to be active either for transmitting or reflecting light rays.

-. T his is more particularly the impression at distances ranging above one hundred feet.

This is a continuation of application S. N. 606,301, filed Dec. 11, 1922, Lenses, by the same applicant, and a continuation in part disclosing matter reserved for separate application and divided out of S. N. 747,015, filed October 31. 1924, which application; has developed into Patent 1,67 0,011, of date May 15. 1928.

What is claimed and it is desiredto secure by Letters Patent is:

A traflic signal glass circular lens having a convex outer side, said lens having rearwardly from said convex outer side a marginally peripherally projecting flange, said lens 0ppo'sitely from said convex outer side and out of the plane of said flange having in a central region and integral with said flange a mirror reflecting surfacefronting toward the central portion of said convex outer side.

In witness whereof I aifix my signature.
